First off, I'm not rooted or anything and still have the stock firmware. Last week my phone was making notification noises when there was no notification. It would do this every few hours or so. I searched for the rogue app that may have been causing it and even installed aLogcat to try to find what was going on. No luck. I wiped my phone and reinstalled almost all my apps again and everything was fine for almost a week. Now my phone is doing the same thing with phantom notification sounds. Any ideas as to what's up?
